[Q] Restore Galaxy S back to Original Android 2.1

Hi All,
I Upgraded my Samsung Galaxy S to Froyo 2.2. All seems well but the performance does not seem all that great as well.
If i want to restore back to the Standard Manufacturer Firmware (i was on JG4) that comes out of the box with the I9000 what do i have to do? Any help here would be appreciated.

Download the firmware from samsung-firmwares and flash your phone with odin. There is plenty of flashing tutorials about to show you how to do it. Although if you managed to update to froyo then you properly already know how to flash it again

Hello. I managed to get the firmware from samfirmware.com for the original 2.1 (Asian version) but I couldn't get it to follow through. There would always be an error with regards to MD5 or something. What do I do? Thanks

I have the same problem as well, any helps here please?

Alot of the the DXJG4 firmware out there is corrupted.
So, try download DXJF4 from samfirmware.com (and flash with Odin with 513 pit) then uprade to DXJG4 through KIES.
NOTE: If KIES says "Device version's cannot be upgraded". Then you need to change your product code back to "XSO" (Search the forum on how to change product code.... about editing the nv_data.bin file)
My Flash history:
DXJF4-->DXJG4-->XXJPK-->DXJG4

I'm pretty new....
The firmware versions you guys are talking about are I hope, all "software" version and not real hardware chip revisions?
thanks

why dont you just flash your phone with 2.2.1 or 2.3.3(latest).....i know 2.2 is quite unstable FW but 2.2.1 will help a lots......I dont think you need to downgrade the phone back to the stock FW to solve any problem

[Q] Should I downgrade my Bell JK4 2.2 to 2.1 before it bricks?

Hey all you fellow sad bunch of Bell Galaxy owners,
I did the bell upgrade via kies, did factory reset, cache wipe, format sd card and so far my phone is running just dandy on the new froyo.
I did it because it was all official and now I see that they pulled the update! And looking at all these threads it looks like this will brick my phone in a matter of days simply because of bad software, not hardware.
Should I try to downgrade before I'm doomed? And where do I find the old bell files to do this odin thing?
Any advice/curious musings would be greatly appreciated.

Yes.
I had mine on jk4 for a day and then changed firmwares. No issues so far.
I'm running jpu now.

Thanks! Hey it's not clear to me as to what is the best route to do the downgrade for the i9000m, and which roms are compatible with this bell version, can I install any rom and be fine?
I have the idea that the i9000m is quite different from the other galaxy s variants.
Rom manager doesn't work on this phone so I guess my only option is odin?

From what I understand, failure is mainly caused by a data corruption on the SDCard when changing firmware. So I'd stay away from frecquent firmware change for now...the more you do it, the higher the risk is.
JK4 is still official, so if you get issue with it, you're pretty much covered by the waranty.

I did mine and its been fine no problems

Rom Manager won't work on JK4 stock because it installed 3e recovery which checks that update.zip files are signed before running them. If you choose to stick with JK4 and want to pursue Rom Manager, your best bet is probably using a kernel which has Rom Manager built in. For example, I flashed SpeedMod Kernel k10j on one of my phones (check the i9000 dev forums).
If you choose to "downgrade", use Odin. JK3 (2.2) and JH2 (2.1) are Bell specific firmwares. Alternatively, using the reg hack solution might work (I've never used it myself so can't offer help). Let us know if you need help with Odin or flashing an earlier firmware.

How do I downgrade my Bell Vibrant? I have 2 Bell Vibrants.. 1 already got the SDcard error 3 days after updating to 2.2.. My second one is still working (2.2) and I want to save it! Please show me how to safely downgrade back to 2.1

Bricks were happening before Froyo 2.2 (JK4) came out of the official channel (Kies).
Nobody can say for certain that it has something to do with JK4 or with an internal hardware issue that is a ticking time bomb. If your phone is working fine on 2.2 (like mine), enjoy it, otherwise send it back to Bell for repair when it dies.

1) Verify you have Recovery and Download mode still working (3 button combo).
2) Remove any lag fixes if you have applied them and download the UGJH2 PDA from Samsung firmware website.
3) Start Odin and put the JH2 firmware (tar file) in the PDA section.
4) Put the 512 pit file that came with Odin install in the PIT section.
5) Click Re-partition.
6) Stop Kies if running and connect phone to USB cable.
7) Ensure that Odin recognizes the phone in the ID:COM section.
8) Click Re-Partition and hit Start.
9) Pray that it works, wait for it to reboot and wait for it to startup, it may take longer than normal for the first boot.
I'm not responsible if it does not work out for you.... Personally, if you have it working on JK4, I would leave it well enough alone.

Thanks for giving the step by step guide.. I am experiencing some FC's on JK4.. I think it's on it's way to getting bricked.. I wana put back JH2 as soon as possible

I went back to JK3 as I've had no problems with it and it's given me the best battery life. Its currently sitting at 84% remaining battery after 12 hours use.

[Q] Gapps on Galaxy TAB? Advice Required

Hi All,
I am an idiot. I tried to install Gingerbread on my TAB, took a back-up, but in trying to reinstall it I lost my way and over wrote the back-up.
I have a working Tab, I can make calls and browse the web, but I've lost Gapps - which means no contacts, no account on the phone, and no access to the Marketplace.
I need to reinstall Gapps. But I don't know how. I've installed Heimdall but not used it, and I believe Odin might be an option. I might have to use ADB even...? I need a step-by-step tutorial.
I've been looking for two days and can't find precisely what I need. Can any one help with idiotproof instructions on how to reinstall Gapps using any method not involving the Marketplace? Is there such a method?
Checked my phone:
PDA: P1000XWJJ7
Phone: P1000XXJK5
CSC: P1000CPWJJ5
Any help appreciated. Thank you.

I can't give a step by step because there are so many already out. You will need to reinstall the full version of what ever rom you have now or restock it to a known stock version that is for your tablet version. Oldin it seems is the way most people do this process.
Re stocking means using odin3 1.7 to repartition with a .pit file, then flash an unrooted rom, reroot, install su and busybox. If you have a custom rom this is the time to flash it.

Okay, so I fixed it! As per instructions, I downloaded Odin, went to samfirmware.com and initially d/led P1000XXJK5, as I thought that fitted my Baseband version (look in "About Phone" in settings). But there was only one .tar file in there, for the PDA slot of Odin.
I also d/led the P1_EUR.pit file (google it, it's on download sites). I put the phone into download status and hooked it up to the laptop AFTER starting up Odin, as per the instructions. I installed the PIT file, as per instructions. I put the Tab in download again and d/led the PDA .tar file.
Odin installed the software okay, but it didn't reboot. Damn.
So I looked on xda and saw that JJ4 is a 'full flash'. Hmm, I thought. So, I d/led that, saw that there were three .tar files and was very excited.
Did a repartition and installation of JJ4 on Odin (combined the steps) and 5 minutes later I had a rebooted Tab - albeit in cyrillic (Greek or Russian - not sure which; sorry).
I have had three days of terror as I thought I'd never get to use the damned thing again. I probably shan't install superuser one click again, and I'll probably stick to Market to get my updates. But am really chuffed to be back on the Tab again...!

Okay, last niggle, I have a ROM on my Tab which cannot be updated thru Kies. If I truly want to get back to a stock ROM as recognised by Kies, is there a way?

I had the same problem. It seems that once install rom from Samfirmware.com or other custom rom; Kies cannot recognise the firmware and will never be able to update any firmware from Kies. I tried to regain Kies trust to check my firmware but fails. Still waiting for a solution. As for now, I'm sticking to not using Kies for rom update but merely installed for its USB driver.

Kies Update
So, it seems I am in luck!
My GTab is currently updating, from
JJ4 - JMI
JID - JMA
JJ2 - JM4
I guess this will restore me to a complete factory version of Galaxy Tab firmware...?

GT-P1000 Ver. 11.04.13.03
Seems the update version is GT-P1000 Ver. 11.04.13.03?

[Q] Trying to update to Gingerbread through Kies but it just loops?

Hi,
I'm trying to upgrade my firmware through Kies, as I've just connected and it's alerted me that I am now able to upgrade to PDA:JVN / PHONE:JV1 / CSC:JV5(OPS). I am currently on PDA:JP5 / PHONE:JP3 / CSC:JP4(OPS), but when I click on the upgrade, it will pop up with a window that looks like it's downloading the firmware, but they disappears as quickly as it appeared, and my phone then needs to re-connect to kies...
This appears to be an infinite loop, without ever really getting anyway. My phone is rooted if that matters, and I don't think I have any lag fixes applied? I know I have applied lag fixes before, but I think I've since flashed with the stock 2.2 firmware, so there shouldn't be any lag fixes going on... :/..
Does anyone know what I'm doing wrong or how I can better debug this problem?
Thanks in advance

If you have the 3 buttons combo, prefer Odin...

Kies is Satan Tool, its a big cup of ....
if u want do upgrade use just and only ODIN

Thanks for the replies..
I would much prefer to use ODIN too, however I don't want to loose my installed apps and how I've got my home screens set up etc, so this is why I was trying to use Kies. I'm not familiar enough with ODIN to know if there is a way I can use it to upgrade without losing installed apps and home screen layouts etc??
Thanks
Denno

Well i think if u backup ur apps then u can save them otherwise i dnt think they remain on ur phone while using the odin is simple.
just go to www.samfirmware.com make an account and chk the firmware sec in toolbox and then select ur model and download the latest formware...JVR is the latest firmware on samfirmware download it and download odin extract that downloaded folder and u have 4 file 1 pit file 2 code 3 csc 4 modem.
Now open odin and put these file respectively ( dnt forget to close kies if u have even from running services on windows) now put ur phone in download mode and connect through odin and tick the repartition on leftside and then start odin...
Of all goes well u r on stock GB
wait phone to phone to boot
now choose any kernel to root ur phone and again turnoff ur phone and get in download mode and choose that kernel in pda option of odin and this time unchk the repartition and start odin
now ur rooted

thanks for the reply Ali Khalid... I'm looking on samfirmware, but I'm not able to find the Gingerbread firmware version for Australia? I downloaded I9000XWJVN ## under the 'America Australia Samsung I9000 Firmwares' heading, but that only had a tar file, with a heap of files I didn't recognize..
Any chance you could give me some more direct help? Like exactly which one I should download for Australia? Looking at the country letter code, which is DT for Aus, they only have firmwares for 2.1 and 2.2...
I'm really lost with this upgrading thing :/..

Can someone please help? I need to know which firmware I should download from samfirmware for an Australian I9000...

Is there a specific reason you need Australian version? You can flash any firmware you wish.
Sent from my GT-I9000 using XDA App

There isn't a specific reason... I thought I would have to go with the Australian one to be sure that calls and stuff can connect to my phone through the network correctly? I'm completely lost with all this stuff to be honest...
If I don't have to get a specific Aussie one, which one should I download? As I mentioned earlier, I downloaded one called I9000XWJVN ## but it didn't have the pda files and pit files as expected.. they were all different things :/..

Im running JVS 2.3.5 (with JVR modem) I haven't bothered to flash an Australian/Optus csc but i guess you can if you wish. I did have to add APNs but that is no big deal.
After that you might want to flash a non-stock kernel for root, lagfix etc. I am running semaphore 1.7 and stock+ theming for extended power menu, %battery crt off etc.
Keep in mind if you are going down this route you will be voiding any warranty you have but ask anyone here it is worth it to make the most of your phone.
Do some reading around the forum and ask any questions you need so you know what you are doing.

Thankyou for your reply Mrlwik, but it's gone totally over my head. I really don't understand any of that.. I have flashed stuff to my phone before, but it was easy because I already had the 3 required files, and there was a step by step..
I guess I could just pop over to the custom roms sub-forum and download one from there and give it a go again..
Do I need to get a special modem or csc file or something to make sure it'll still work with Optus?

Sorry I was really confused once too, I will do my best to break it down a little.
You don't need a specific modem for Optus although different modems will give different results depending on your location regarding signal, 3g, gps and battery (due to signal strength) its quick and easy to change modem and this can be done anytime (through CWM recovery) without any data loss.
CSC is a bit different, although you can use a CSC that is different to your location/carrier it basically denotes any specific apps and APNs. CSC can be changed with odin but will factory reset you phone and you will lose data.
-APN details can be found with a quick Google search and can be added no problem through settings>wireless and network>mobile network>access point and as I don't care for carrier specific apps (apart from "my account" but the .apk for that easy to find) I haven't bothered to change it. Others do find it important.
I know the stock 2.3.5 JVS from samfirmware will contain the 3 files (code, modem, csc) and the .pit file for flashing because it is what i flashed.
Or alternitavely there are a few custom roms that can be flashed through odin regardless of what firmware and bootloaders you are currently running.
Some firmwares/ROM only have one file and it can be flashed under PDA. There are guides for flashing on samfirmware(for stock), here and video guides on YouTube. Always stick to the guide.
Decide what direction you want to take (stock with non-stock kernel or custom rom) and read up on some of the topics in the general section about flashing and/or any topics relating to any ROM you want to flash.
Once you know what you want to do with your phone it will mean much less reading for you and others will be able to help you more as you will know what questions to ask.
There is lots of info here, its just a matter of knowing what info you need and how to find it.
Hope that helped a little..

If you phone is rooted download titanium backup and backup all apps before flashing, then install it again after flashing and restore only apps.

Wow thankyou so much for that breakdown Mrlwik! That does actually help a little! I'm going to find a stock firmware from samfirmware instead of a custom rom.. But it's great to know that I can swap modems to try and find the one that best suits my needs, as I do have problems with reception in my house, so maybe a new modem could fix that?
Anyways, thankyou again, and great effort and writing all of that with your phone! It definitely helped

Well I finally took the plunge and flashed my phone. I used the JVS firmware, which worked seamlessly. Then I wasn't sure if I were still rooted or not.. so I downloaded Dark Core (or something), and flashed that in PDA using ODIN. Then I was definitely sure I was rooted . Now I've just got to figure out a 'lag fix', my quadrant score at the moment is ~1400, but I reckon I can get much better, so I'll try some overclocking apps from the market I think, see which works best for me.
The most painful thing is restoring all my apps using Titanium Backup.. I have to click install for everyone of them, it doesn't automate it, which is so very annoying, but I'll get there eventually :/... lol
Thanks for all your help Mrlwik, very greatly appreciated

I had a similar problem with KIES in South Africa.
I don't use KIES any longer, it doesn't even have the "connect to internet" option.
Since you've rooted your device, I'm sure you have Clockworkmod flashed...if not, flash that using Odin. After that, you can flash any ROM, custom or stock, using clockworkmod recovery, then you don't require Odin again...just copy the ROM or apps you want to flash to your phone, boot into recovery, flash, and restart. Can't be easier than that.

[Q] Roms with GKG3 based firmware

Hey everybody,
Im kinda new to droid development, and have played around with it a little (flashing roms, kernels, rooting etc) however, im curious why there are roms based on pretty much every other firmware other than GKG3. I might sound like a n00b for asking about this but its mainly for my knowledge. I figured KG3 would be fairly common as it is one of the North American firmwares, but I must be incorrect? Anyways any insight on this would be great. Also a quick question, seeing as I am a Bell I9000m SGS owner does it matter if I put firmware from say Europe on my phone? I have noticed that my signal decreases when I put a rom on that is JVR based? Curious if this causes my phone, seeing as the modem is being changed to JVR, to think that I am out of country and will inflict long distance charges. This probably sounds like a dumb question, and I dont really believe LD charges will apply, but some confirmation would be nice as google didnt really help me out on this one.
Thanks!

KG3 is 2.3.3 and although it was just issued to Bell and other N.American customers, the rest of the Anfroid world has been using 2.3.4 for 6 months and some have moved to 2.3.5. The roms you see here are cutting edge and most use the latest firmware. The last official and stable release was JVR a 2.3.4 firmware and there are many good roms for JVR. It is easy to keep your KG3 modem in place and the KG3 CSC file and just upgrade your system to a custom JVR kernel and JVR rom.

I tried flashing galaxian's jvr kernel and it just bootlooped so maybe I'm doing this wrong? I kept my stock modem and CSC, flashed kernel using oden, factory reset was done as well as a cache clear prior to the flash and all I'm getting is a bootloop so I'm not entirely sure what I'm doing wrong any advice would be appreciated! And again thanx for the info in the previous post!

yes you flashed just the kernel, you must first flash the stock rom and then any custom kernel for the same firmware -- you need the stock rom to install the correct bootloaders prior to flashing the custom kernel
so in odin, flash JVR stock in pda, KG3 in phone and CSC
tick auto re-boot
then flash the custom kernel of choice in odin under pda

Awesome thanks for the tips! Will give this a try

Hi guys - you guys might be able to help with a wee problem.
upgraded FW today via kies to 2.3.3 KG3 from froyo 2.2 with speedmod kernel.
in the process though i lost root but worse is i now don't have 3BR, when i used to. I still have 3 button download mode though.
I want to root again and flash a different kernel (for root but also for performance/tweaks) but worried to without 3BR ie. how will I access tweaks/enable root etc without it!?
Any ideas/advice please? Thanks

first flash a complete 2.3. firmware, either 2.3.4 JVR or 2.3.5 JVT. This should re-install basic 3BR functionality. I think you have not got the necessary bootloaders in the jump from froyo to GB and a complete stock install should correct this. Do tick re-partition and use 512 pit, do check auto-boot: let the phone boot and right itself. Check for 3BR and do a system reset.
Then flash KG3 modem and CSC. Your phone should then be functional.
Then flash a kernel with root inbuilt to it.
If you use the GTO Tornado kernel you can also clean your system completely as this stage instread. If you use another kernel, do the factory reset, davlik cache clean etc. prior to flashing the kernel as suggested above.
Do the clean prior to re-installing your apps.

Thanks! will give this a go but have only ever really flashed a kernel before with odin so want to be doubly sure about these steps if that's ok? apologies for my noobish ignorance
- only found a 2.3.4 JVR at samfirmware - getting this and the 512pit file. This should be fine?
- then flash a KG3 modem and CSC - any idea where I get those files from? - the ones i've got now i only got through kies (and when i do get em, when i do this in odin do i only use the phone/csc boxes and leave pit empty/uncheck re-partition?
thanks again mate.
Edit: forgot to say my reason for questioning the JVR is because the one i have is listed as European...where as I have a bell mobility but in australia - does this matter? latest FW for aus/america is JVN 2.3.3

no problem: always better to ask for help first then assitance fixing a problem when it all goes pear shaped.
There is a thread on the KG3 firmware with lots of these questions answered: http://forum.xda-developers.com/showthread.php?t=1211939 and also the basic resource for firmware posted by Ramad here: http://forum.xda-developers.com/showthread.php?t=1102881 -- scroll down and you will find KG3 under N.American, he also has a nice set of illustrations for using odin.
You can also source a cwm zip for the KG3 modem from perka's stash here and on the market (free app) -- useful to havce the modem in cwm zip form as then you can just install a new stock firmawre such as JVR or JVT and add the modem in recovery.

Thanks so much again - that looks like a hefty bit of reading to be done there via your links so before I do that, just one more Q please - and apologies if the answer for this is somewhere in the links you've provided.
i was just trying to read up about why the samfirm file extracts only to a single .tar file called JVR_JVR_JVR and how to use that in Odin and came across this thread:http://forum.xda-developers.com/showthread.php?t=1075278
my Q is - in this thread he makes a strong point of stating not to tick repartition and not to put the .pit file...but you say to do so.
am i missing something obvious?

well different people different perspectives on re-partition and pit.
Tick re-partition and flash the pit file. Leave it un-ticked and do not flash pit file. That's the only key: do one or the other.
As I understand it, the reason to re-partition is that it re-sets the base file system upon which you are now flashing the stock firmware -- seems a basic step whenever you move firmware versions e.g. 2.2 to 2.3, 2.3.3 to 2.3.4 to 2.3.5 -- not so much if you are installing a rom or kernel within that family of firmware.
Since I always then convert the file system to ext2 to speed up the system and I use damain's kernel to clean the system, I do use the pit file whenever I flash a new stock firmware to clear the basic file system and further aid removal of legacy files that could complicate the install.
---------- Post added at 09:28 PM ---------- Previous post was at 09:24 PM ----------
BTW the samfirmware files do extract using 7zip into the component parts for use in odin: pda (rom) phone (modem) and CSC. You then flash a custom kernel in the pda section if you use one for performance and root.

thanks lgssheddon, for the info here and in the PM.
Will crack on now with reading all the links you provided.
I just have to say a big fat D'oh! - why oh why could I not find the answer to what was bothering me most ie. apparent loss of recovery mode. The very first post in the first thread you linked gave me the answer - that it is now a 2BR (and tried it on my phone et voila, by magic I can get into recovery again!). Don't know how I could not find this thread even when I searched "KG3"!!
Thanks again for your help. i'l llet you know how i get on once i digest all this info

I want to root again and flash a different kernel (for root but also for performance/tweaks) but worried to without 3BR ie. how will I access tweaks/enable root etc without it!?
Any ideas/advice please? Thanks

The 3 button recovery has changed for KG3. I believe it used to be upvol home and power. I do believe now it is volup, voldown, and power. This should work for you to get you into recovery to flash whatever you like. Also the samfirmware for JVR is branded with Swisscom and doesnt work very well for using it with a KG3 modem and CSC, with my experience anyway. I would recommend to go to a JVQ PDA and use KG3 for your Phone and CSC. Also after you have installed this make sure to check what your country code is and install it. Hope this helped

The firmware that he is referring to doesn't. It is only one file meant for the PDA section of ODIN. Not entirely sure why they did this but i was running into problems with it as well. If you know how to play around with the core files you could in theory extract it to its root and put multiple files into .tar files (ex. select factoryfs.rfs, param.lfs etc. and place it under one .tar) but thats a lot of playing around and potentially dangerous if not done correctly.

not sure which download you are referring to but there was a branded version of JVR and a generic one on samfirmware: I have the one that does not have the swisscom logo and it certainly was extracted by 7zip into its component files (pda/phone/CSC) as they are still on my pc in that format.
You can also source stock firmware from Ramad's thread.
And I stand by my comment that for anyone using KG3 as a modem, JVR is the most stable official release available, much better than JVQ. JVT has a lot of promise and will be a better firmware than JVR but it is not yet had all the bugs sorted and while there are Gold Rom version for JVR any JVT rom is still at a beta stage and should not be used yet by someone just starting to flash custom firmware (IMO).

Hi again,
Q for lgssshedden really but if anyone can help i'd appreciate it!
have had 2 crashes now with Tornado Aureus RC1 - few little bugs/glitches eg with ringtone changing etc then on a reboot it won't go past the Tornado start screen with the big flame.
First time I just reflashed stock KG3 then reflashed the Tornado kernel, no problem. This time when I try to flash the Tornado kernel (either Aureus RC1 or Gold) it just bootloops at startup even though the flashing seems to go ok.
So now i'm back to (yawn) stock KG3 2.3.3. Really just want to root it again but with Tornado not seeming an option i'm finding it hard where to turn to root.
Thanks in advance!
